How big imagesize for guild?

[KratosAurion]

Not that "i'm" going to make a new guild or w/e, im just curious. Or if it resizes the image does it capture every detail of the picture, but just harder to see?
~thanks in advance.

51x51 pixels.

You must set your guild icon as that size for it to even accept your icon.

It depends on your image and how you resize it. Generally, you wouldn't want to get a picture generally used for backgrounds and instead would get small pictures of items and focus on that.

At level 10, the size increases to 81x51.
